Hey we are trying to get started with the tutorial project. We have followed the docs to thoroughly and still can’t get it to work.

In our browser we receive the following error:  
Exception: Required service ‘Litium.Search.SearchPermissionService’ is missing.

We have reinstalled all the packages as instructed.

Best regards.

What docs did you go through? Why do you choose 7.2.3 instead of the latest one?
